PUR5115 Black PUR Polyurethane Hotmelt Adhesive
PUR5115 is a Black PUR Polyurethane Hotmelt Adhesive that consists of a single-component reactive polyurethane that is entirely solid. When applied in a warm state and subsequently solidified within the bonding area, this adhesive delivers strong initial adhesion. A secondary curing process further cross-links the bonds, enhancing their elasticity and structural resistance to moisture. Once fully cured, the product remains solid without melting.
Features and benefits
- Enables prompt processing due to its high initial strength
- Can be applied using automated heating systems without creating strands
- Adheres effectively to various materials, including plastics and metals
- Behaves as a simple one-component hot-melt glue during application but evolves to establish a durable, cross-linked structure similar to a robust urethane polymer over time.
